Cooling System Water Temperature Regulator - Replace
在水溫調節器出現故障之前更換水溫調節器。 這是建議的預防性保養措施。 更換水溫調節器可減少發生計劃外停機的機率。 請參閱本操作保養手冊, "保養週期表"部分,以瞭解合適的保養週期。
如果水溫調節器在節流開啟位置出現故障,可能導致引擎過熱或過冷。
如果水溫調節器在閉合位置出現故障,可能導致過熱。 過熱可能造成汽缸蓋破裂或活塞卡死問題。
如果水溫調節器在開啟位置出現故障,將導致引擎在非滿載作業時溫度過低。 如果引擎在非滿載作業時溫度過低,可能造成汽缸內積碳過多。 積碳過多可能導致活塞環加速磨損以及缸套磨損。

若未定期更換水溫調節器,可能會造成引擎嚴重損壞。 卡特彼勒引擎包括一個分路結構冷卻系統,並要求運轉已安裝水溫度調節器的引擎。 若已不正確地安裝了水溫調節器,則引擎可能會過熱並導致缸蓋損壞。 應確認新的水溫度調節器安裝於原來的位置上。 請確認新的水溫度調節器安裝在原來的位置上。 切勿在密封墊或汽缸蓋表面使用液態密封材料。 |
請參閱拆卸與組裝手冊, "水溫調節器 - 拆除以及水溫調節器 - 安裝"這兩篇文章,以瞭解水溫調節器的更換程序,或諮詢您的 Caterpillar 代理商。
附註如果只更換水溫調節器,請排出冷卻系統的冷卻液,直至液位低於水溫調節器殼體。
